Revolution Liquid Highlighter (£6) is a liquid luminising formula that can be mixed into face or body lotions, BB creams, or liquid foundations to add a lustre to the skin. Want to ramp up the glow? Use a sponge or brush to apply this to the high points of your face. The drops come in this champagne hue, as well as several other out-of-this-world holographic shades that will give you a glow you could spot from outer space.
